  • Catheter with combined position and pressure sensing structures
    Patent number: 9492104
    Abstract: A catheter is responsive to external and internal magnetic field generators for generating position data of the catheter position and pressure data to determine pressured exerted on a distal end of the catheter when engaged with tissue, with a reduced number of sensing coils and reduced number of sensing coil leads for minimizing lead breakage and failure. The catheter includes a distal section adapted for engagement with patient tissue, where the distal section has a proximal portion, a distal portion and a flexible joint with a resilient member adapted to allow axial displacement and angular deflection between the proximal and distal portions of the distal section. The catheter may have three or less sensing coils with three or less leads, each transmitting signals between a respective sensing coil and the signal processor.
